Question: When did the sole surviving son create a new tax on income and movable goods?
Context: Document 1: John, King of England: The result was a sequence of innovative but unpopular financial measures.[nb 10] John levied scutage payments eleven times in his seventeen years as king, as compared to eleven times in total during the reign of the preceding three monarchs. In many cases these were levied in the absence of any actual military campaign, which ran counter to the original idea that scutage was an alternative to actual military service. John maximised his right to demand relief payments when estates and castles were inherited, sometimes charging enormous sums, beyond barons' abilities to pay. Building on the successful sale of sheriff appointments in 1194, John initiated a new round of appointments, with the new incumbents making back their investment through increased fines and penalties, particularly in the forests. Another innovation of Richard's, increased charges levied on widows who wished to remain single, was expanded under John. John continued to sell charters for new towns, including the planned town of Liverpool, and charters were sold for markets across the kingdom and in Gascony.[nb 11] The king introduced new taxes and extended existing ones. The Jews, who held a vulnerable position in medieval England, protected only by the king, were subject to huge taxes; £44,000 was extracted from the community by the tallage of 1210; much of it was passed on to the Christian debtors of Jewish moneylenders.[nb 12] John created a new tax on income and movable goods in 1207 – effectively a version of a modern income tax – that produced £60,000; he created a new set of import and export duties payable directly to the crown. John found that these measures enabled him to raise further resources through the confiscation of the lands of barons who could not pay or refused to pay.
Document 2: John, King of England: After Richard's death on 6 April 1199 there were two potential claimants to the Angevin throne: John, whose claim rested on being the sole surviving son of Henry II, and young Arthur I of Brittany, who held a claim as the son of John's elder brother Geoffrey. Richard appears to have started to recognise John as his heir presumptive in the final years before his death, but the matter was not clear-cut and medieval law gave little guidance as to how the competing claims should be decided. With Norman law favouring John as the only surviving son of Henry II and Angevin law favouring Arthur as the only son of Henry's elder son, the matter rapidly became an open conflict. John was supported by the bulk of the English and Norman nobility and was crowned at Westminster, backed by his mother, Eleanor. Arthur was supported by the majority of the Breton, Maine and Anjou nobles and received the support of Philip II, who remained committed to breaking up the Angevin territories on the continent. With Arthur's army pressing up the Loire valley towards Angers and Philip's forces moving down the valley towards Tours, John's continental empire was in danger of being cut in two.
